First, I have to say Kyle Larson is superman, so there.
But the reason for this thread is I have a question. The wings are adjustable during the race, I think everyone knows that. But how? Is it a switch or a lever, got any pics? Im standing 20 ft away and I want know what do they start the race with, when do they change it and why. I don't need a bunch of numbers, tell me what's going on so an idiot like me can understand. And please don't point me to another thread, that's a weak answer. Thanks
Dave

The wing ram is hydraulic, driven off the power steering. There is a valve on the left side of the frame about level with the stering wheel, and the driver reaches up with his left hand to move the wing. Typically you start with the wing about 2 inches from fully forrward and pull back to tighten up the car as fuel burns off and the track slicks off. If you are in the pits for engine heat, look around as the cars pull in and you will probably see some drivers cycling the wing back and forth a few times while sitting at the trailer idling.

See, I thought it worked the other way, full back and then forward, but like I say, with these gizmodic things I'm a complete idiot
Thanks

Not directly. As the wing moves back the rear wing tree stands up, so moving the wing back indirectly increases the wing angle. In theory you could plumb another hydraulic ram to do that.
I remember a long time ago someone came up with a way to hydraulically move the wing left and right. Not sure if that was outlawed or if it's just too complicated.
Signature here.

No, pulling it back also increases the angle creating more downforce which is what you need when the track slicks off.
